intro
Purpose:
- Preliminary look at hi/lo multivariate contrast (cross-validated euclidean) in each task.
- Preliminary qualitative comparison of effects of prewhitening and pattern standardization on multivariate contrast.
Notes on analyses:
Target TRs:
- Axcpt: 7, 8, 9
- Cuedts: 9, 10
- Stern: 11, 12
- Stroop: 2, 3, 4
Contrasts (cross-validated euclidean):
- Axcpt: \(\text{BY} - \text{BX}\)
- Cuedts: \((\text{InConSwitch} + \text{InConRepeat} - \text{ConSwitch} - \text{ConRepeat})/2\)
- Stern: \(\text{LL5RN} - \text{LL5NN}\)
- Stroop: \((\text{PC50InCon} + \text{biasInCon} - \text{PC50Con} - \text{biasCon})/2\)
Network-level
Estimates are first averaged across parcels within network per subject. Group-level stats and plots are then displayed at the network-level.
